对于有源RIS,作者首先推导BS发射信号功率和RIS输出信号功率之间的最佳功率分配。作者还分析了各种系统参数对最优功率分配比的影响。当具有相同的不是很小的总功率预算,并且RIS元件的数量不是很大,有源RIS将优于无源RIS。 目录 Research Objective Problem Statement Methods Evaluation Conclusion Reference
33 down vote favorite 13 Is it correct to say that everywhere recursion is used a for loop could be used? And if recursion is usually slower what is the technical reason for ever using it ove
Accuracy Versus Precision A surveyor strives for both accuracy and precision. Many people use the terms “accuracy” and “precision” interchangeably. However, for those in the surveying profession (a
